HEATING STOVE.

Application filed September 22, 1927. SerialNo. 221,238.

This invention relates to heating stoves in which liquid fuel is.converted into the vapor phase before it enters the burner. In suchstoves, a heat responsive vaporizer, commonly called a generator,communicates with a tank containing liquid fuel under pressure. Theliquid fuel forced into the vaporizing generator by the pressure withinthe tank is Va porized and passes into an intake port in a burner whereit is burned. The tank obviously must be filled from time to time, so Ihave provided a novel removable unit consisting of the tank, avaporizing generator and a heat insulating plate for the tank, allarranged in a unitary structure so that the unit can be convenientlyremoved for filling the tank, for inspection and repairs of the partsthereof and for testing the same. The vaporizing generator must ofnecessity be preheated in order to vaporize the liquid when the fuelfrom the burner is first ignited, so I hate provided a preheater whichmay be a part of the unit. This preheater can be conveniently carried bythe insulating plate which serves to insulate the heat from the tank tothereby prevent the highly volatile liquid from becoming dangerouslyhot.

I have found it expedient to make certain other improvements in a vaporgenerating stove, all of which will be specifically referred tohereinafter, reference being had to the accompanying drawings in whichFig. 1 is a front elevational view of a stove constructed in accordancewith my invention, parts bein broken away to better illustrate certainoter parts. Fig. 2 is an end view of the stove, the end door being swunginto open position.

Fig. 3 is a perspective view of the removable unit and Fig. 4: is anenlarged view of the preheater; partly in section and partly inelevation.

Referring, now, to the drawings by numerals of reference, 1 designatesthe casing- 9. The unit is best illustrated in Fig. 3' as comprising atank 10, carrying bands 11 and 12 which support a pump 13 having aconduit 14 leading into the connection 15 communieating ,.with the tank.The connection is provided with a valve 16 closing ofl communicationbetween the conduit 14 and the tank when the pump has suppliedsufficient pressure. There is a pressure gage 17 also communicating w1ththe connection 15.

Leading from the tank 10, below the liquid level thereof, is aconnection k8 having a valve 19 which is adapted to open and closecommunication between the tank 10 and a conduit 20, connected to avaporizing generator 21, supported by the brackets 22 and 23, carried bythe heat insulating plate 24 for the tank supported by the bands 11 and12. The vaporizing generator 21 has an outlet tip 25-which can be openedand closed by a valve (not shown) on the end of the stem 26. The stemmay be operated by a hand wheel 27 The particular construction of thegenerator is not shown nor described because such vaporizing generatorsare well known. 'The'preheater is shown as consisting of a reservoir orbase 28 secured to the plate 24 by a fastening device 29. The particularconstruction of the preheater constitutes no part of my invention as theone selected for illustration has been in use prior to my invention.Briefly, it consists of a reservoir 30 adapted to be supplied with fuelthrough an opening 31. The liquid is carried up into the space betweenthe tubes 32 and ings 35. The fuel can be ignited above the wick andsince the preheater is below the generator, the generator will beinitially heated so that the liquid supplied'from the tank will bevaporized. After the fuel from the burner 2 is ignited, the flamepassing out of the orifices 5, oflset from,-and communicating with theburner manifold, will im pinge upon the generator 21 and keep it hotenough to vaporize the fuel in the vaporizing generator so long as thestove is in operation. The tank can be filled with liquid through anopening closed by the filler plug 36. The unit can be introduced intothe stove by sliding it along the guides 6 and 7 until the ti 25 of thevaporizing generator alines with the inlet port 3 of" the burner. Whenit is desired to fill the tank, to inspect any parts wish to be limitedto the exact details of construction shown, but reserve the right tomake changes in form, proportions and minor details of constructionwithout departing from the spirit of my invention or sacrificing any ofits advantages.
